SPECIFICATION forming part of Letters Patent No. 776,628, dated December 6, 1904. Application filed November 19, 1903. Serial No. l8l.870. (No model.)

1v (L7/Z 7071/0771/ it Hefty cm2/cern.-

Be itknown that we,REINHARDVOGELMANN, a subject of the German Emperor, residing' at Stuttgart, in the Kingdom of lVi'irtemberg' and Empire of Germany, and AUeUs'r F. NANZ, a citizen of the United States, residing' at Brooklyn, in the county of King's and State of New York, have invented new and useful Improvements in lVatchmens Time-Detectors, of which the following' is a specification.

By means of this invention clear and satisfactory impressions are secured, and tampering is prevented or made difiicult, if not impossible.

This in vention resides in the features of construction set forth in the following' specification and claims and illustrated in the annexed drawings, in which- Figurel shows the detecter sectioned along' a' a', Fig'. 2. -Fig'. 2 is a section along 1/ y, Fig. 1. Fig. 3 is a section along' .2', Fig. l. Figs. 4 and 5 show a key. Fig'. 6 shows a die, and Fig. 7 a modification. Fig'. 8 shows the key partly turned. Fig'. 9 shows thekey in printing' or marking position.

In the drawings is shown a key having' a ring or handle part c, with stem and bit or barb c. The key or its barb is shown with a female or sunken die (Z, such as a number, letter, or other notation or mark. A matrixplate or male die is shown at c, and a dial or disk of a watch between the dies can be suitably marked. The key being inserted into its hole or box and given a quarter or other turn, the sp'ringf, acting against the key or barb, will cause the barb to press or snap its die to sit squarely against the dial or face the male die or matrix e, so that the dial receives a mark or impression.

The spring in the example shown is not made to act directly against the barb or key, although practical working devices, with the spring acting' directly on the key and embodying' this invention, have been made. In the example shown the spring' actuates a swinging piece m, pivoted at a to a frameplate 0r suitable point and having' a stud o for the engagement or pressure of the spring.

This piece m can be made L-shaped and might be called a pressure or engaging piece, as it transmits the energy of the spring' to the key at suitable times, and to prevent said plate m from contacting' with the key-pin, so as not to interfere with theinsertion of the key, a limiting-stop is provided for said plate m, and said stop is indicated by the reference character y).

The key has a loose connectionthat is, the barb or stem` and the handle part t are loosely connected. A pin-and-slot connection (indicated at 0) allows a play or looseness between thehandl'e and barb, while still connecting' the parts, so that the barb can be turned by the handle. This loose connection prevents tampering' or manipulating. The user cannot hold back the barb from making' a clear impression, since when the barb has been turned to a certain degree-for example, to the position indicated in Fig. 8-the spring f or engaging device m causes the barb to jump or snap ahead ofsor away from thehandle or bow a to the position indicated in Fig'. 9 and strike or impress the dial to give a clear mark. The loose connection prevents the user holding' back the barb, so as to make an imperfect, unsatisfactory, or tamperable impression. ln other words, near the end of its turn or at about the printing-point the spring' throws the barb to give a printing stroke, the loosenessor play between the barb and handle allowing' the barb suflicient freedom to be snapped by the spring' or propelling devicef.

Then the key is inserted and begins to turn,

the barb of the key, coming against the eng'ag'- ing-piece fm, forces the saine back against the action of the spring' until, as stated, the key has been turned to bring' the barb to a ce1'- tain position-for example, Fig'. 8`when the spring' or piece m presses the barb independently or in advance of the key-handle to the striking' or printing position, Fig. 9.

The case la, is shown with cover hinged .thereto at A fastening or safety pin or screw Z is shown to hold the pintle of the hinge in place, so that this pintle cannot be lost or withdrawn for tampering' 0r otherwise. A
